Camping Ice Packs
Reusable Ice Packs and Freezer Blocks are a low-tech accessory to help keep the temperature cool, and are vital for use in coolers and coolbags. Put them in your home freezer before leaving on your trip, and they will help keep your food and drink cool.
Sizes range from individual packs to large blocks. Smaller packs have the advantage that they can be slotted between food and drink items more easily, and the flexible packs can be wrapped around curves as well. People also use ice packs for injuries as first aid for sprains and aches.
Larger blocks are more useful for filling more void space in a coolbox and will keep cold for longer.
